When people first come into contact with a new thing, they always feel a little novel and excited. Chen Kan has been a student for nearly twenty years. Now he wants to change careers and become a teacher and teach students, and he is inevitably a little excited.

Chen Kan’s first class was not dedicated to freshmen, but to junior high school students. Because freshmen from the Middle School Normal University enrolled one week after the official opening, the students have not come yet.

On Wednesday and morning, the rule of the Middle School Normal University is that two classes are held one after another, and three or four classes are Chen Kan’s classes, targeting students from two classes in history in junior year, and the course is "History of Chinese History".

Chen Kan naturally did not need to prepare for this course at all. This is the most basic course in history, and it is about the history of history. Just like the history of mathematics in the Department of Mathematics and the history of literature in the Department of Literature, Chen Kan naturally remembered this course completely in his heart.

The students are juniors and are already "old birds". They also have their own judgment on the course and teachers. From the name of this course, you can tell that this is another "boring" course. A new teacher who has just graduated probably can't tell anything interesting.

However, all the students came. First of all, Chen Kan, the new teacher, and history, are new things, and they also came to "try it out".

The second and most important thing is that I don’t know if Chen Kan, the new teacher, will name a name or whether he has the habit of name a name, so I still have to come and take a look and look at it. Although university teachers’ teaching has nothing to do with their professional titles, many teachers still like to name before class.

On the one hand, it may be to show the presence of a teacher, and on the other hand, it is also to worry that something happened to the students. If the student does not come in the teacher’s class, the teacher does not notice, and then something happens to the student again, it is a teaching accident, and the teacher is responsible.

For students, if they are named by a new teacher and leave a bad impression on the teacher, then this subject may be difficult, so come and take a look.

One feature of this course is that there are no textbooks, and students come to class empty-handedly because Chen Kan couldn't find a suitable book to be a textbook.

There is no designated textbook in universities. All textbooks are selected or written by the teaching teachers of this subject themselves. However, Chen Kan did not find a suitable book, so he did not choose textbooks, which can be regarded as saving students some textbook fees.

"Chinese history, Chinese history is already a headache, and now it has become two pieces of history, which makes me feel even more boring!" Chen Kan touched his nose on the podium and said.

Chen Kan might have been stage frightened before experiencing the "Captain America" ​​plane, but now Chen Kan does not know anything at all. Chen Kan personally led the army battles and was received by President Roosevelt. Such a situation in class is nothing at all.

With Chen Kan's solid historical knowledge, he can suppress these students in terms of experience and aura.

"Puchi..."

"Hehe..." Many students laughed when they heard Chen Kan's words.

Indeed, many of their students choose history because they have no choice but to do not really like history. They may be to be teachers, or they may be transferred...

Even if some students really like history, they just like history, not history. "History" and "History" are two completely different concepts. After two years of study, they basically feel disgusted with a certain history.

Chen Kan's words can be regarded as expressing their thoughts, two pieces of history.

"To put it simply, it is about the development history of the discipline of history. In the first lesson, let's put aside history of history and let's talk about history!" Chen Kan did not name or introduce himself, and went straight to the topic.

"This is completely different from the history you have learned before. We don't talk about boring historical materials or advanced theories. Now I'll ask my classmates a few simple questions here."

"Um!"

"Why did the ancients know that they could not get married in close relatives?" Chen Kan asked a seemingly idiotic question directly.

"Because the incidence of genetic diseases caused by in-kind marriage is high!" Several students answered at the same time.

Chen Kan smiled, and he expected that he would get such an answer, which seemed to be in a biology class.

Chen Kan stretched out his two fingers and said, "First of all, this is history. You use biology knowledge to explain it. Second, how did the ancients know that close relatives cannot get married? Did they know genetic biology at that time?"

"The ancients could get married in close relatives, and it was normal for cousins ​​to get married." At this time, a classmate retorted.

"Historical records show that 'Men and women have the same surname, and their birth is not a foreigner'. In fact, since the Western Zhou Dynasty, China has clearly prohibited close relatives from getting married. Although it is different from the current regulations within the three generations, it is indeed not allowed. Why? Did the ancients understand biology and genetics at that time?"

"this……"

Looking at the speechless people, Chen Kan continued, "Do you know? The Jews allowed close relatives to get married until now."

"How is that possible!"

The Jews are known as the smartest nation in the world. They have lost their country for thousands of years and wandered around, but this nation has been preserved until now, which is a miracle in itself.

When hearing that the smartest nation allowed close relatives to get married, some students didn't believe it and picked up their phones and checked it. It turned out that Chen Kan was really not nonsense.

Chen Kan waited for a while, but did not answer the question, but then asked:

"Some classmates may have checked my information. My master's thesis is about research on Qin Shihuang. Are you familiar with Qin Shihuang?"

The students just nodded slightly and stared at Chen Kan. They were a little interested in Chen Kan's class, and the teacher seemed to be a little different.

Qin Shihuang, the first emperor in China, was basically a historical figure known to everyone.

"But do you really understand Qin Shihuang?" Chen Kan said with a smile:

"Everyone knows about Qin Shihuang basically only two things. First, the grievances of Qin Shihuang's parents, the true and false father of Qin Shihuang, and the things between Lao Ai."

There are countless film and television works, all of which are filming these laces from the previous generation of Qin Shihuang.

"The second thing is that Qin Shihuang unified the world. You may know the order of unifying the world and the strategy of consolidating the rule, but think about what else do you know besides these things?"

“…”

After listening to Chen Kan’s question, the students thought it was really like this. Whether it was a history book in middle school or a history textbook in university, there was really only this information, and some of it was seen from film and television works.

"Ask you a few questions about people related to Qin Shihuang." Chen Kan continued:

"First, who is the First Queen? This is not a minion. This is a very important person. Why can't I find any words about this person in the literature? This is the mother of the country. The country cannot have a king or a mother for a day. Why did this person disappear?"

"Can it be because of the long time?" a girl in the front row asked in a low voice.

"Sima Qian's writing of "Records of the Grand Historian" is only more than seventy years since Qin Shihuang, so I can't find any record?" Chen Kan asked back, but he did not give the female classmate the chance to answer. Chen Kan continued:
Chapter completed!
